Inland ECDIS Charts

inland vessel drives a canal river along

From Antwerp to the deepest navigation points in the Netherlands, from the French canals to the Danube, the inland rivers will hold no secrets for you when you use our reliable Inland ECDIS Charts.
Zooming in makes the image sharper and more detailed. Inland ECDIS Charts are the preferred choice for inland navigation on European rivers and canals.


Inland ECDIS Cartography (Europe)

Both the raster and vector charts have been compiled in accordance with the global chart standards S-57 and S-52. This applies to both inland and nautical navigation charts. Tresco produces these charts in-house, using data from competent authorities.



Tresco’s team of programmers and cartographers always keeps the navigation charts and software up to date. Any changes in buoyage, new bridges or weirs, relocation of navigation channels, or changes in VHF channels are updated immediately. A maintenance subscription includes three update CDs per year and free telephone, fax, or e-mail support.

Save the file on a USB stick and run the program on your PC with Tresco Navigis.

Leading partners
